most of the time the letter of the chamber was stamped above the VOC stamp, but sometimes below the VOC stamp. Not specificly the "R". I have seen blades with the "R" above the VOC mark, and also with the "E" below the VOC mark.
Alas, indeed I have seen also a VOC blade with the "R" below the VOC mark.
But in general most of the time they are depicted above.
